7980 ÷ 82 
Let's see how many times 82 fits into 7980.

Moving on to step 1:
If we divide 7 by 82, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 82

Let's proceed to step 2:
82 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 82

On to step 3:
82 can be fit into 798 9 times, resulting in a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 738 away from 798, we end up with 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 82

Step 4:
600 divided by 82 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 574 from 600 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 5:
260 divided by 82 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 97.3
Subtracting 246 from 260 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 6:
If we divide 140 by 82, we get 1 and a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 97.31
Deduct 82 from 140 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
The number 82 fits into 580 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 97.317
Deduct 574 from 580 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 82 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 97.317
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
82 goes into 600 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 97.31707
The remainder is 26 after subtracting 574 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
When dividing 260 by 82, we get 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 97.317073
If we take 246 away from 260, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
82 goes into 140 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 97.3170731
If we subtract 82 from 140, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
When dividing 580 by 82, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 97.31707317
Subtract 574 from 580 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 97.31707317 and a remainder of 6e-09.
